Rational Drug-Use Evaluation Based on World Health Organization Core Drug-Use Indicators in a Tertiary Referral Hospital, Northeast Ethiopia: A Cross-Sectional Study

Medicine Prescribing Practices and Prescription Errors Evaluations at Outpatient Department in Debre Berhan Comprehensive Specialized Hospital, Amhara Regional State, Ethiopia

Background: Currently, irrational uses of medicines becoming global problem largely in developing countries like Ethiopia. Inappropriate prescribing is a major cause for poor treatment outcome and higher costs. Hence, this study was aimed to investigate medicine prescribing practice and prescription errors using WHO medicine-utilization core indicators. Methods: A hospital based retrospective cross sectional study design was used to evaluate prescribing practices and prescription errors from September to October, 2024 at the OPD pharmacy using systematic random sampling technique while a prospective approach was employed for facility indicators. Presence of potential drug-drug interactions (DDIs) were evaluated using Medscape Online Drug Interaction Checker. Data were analyzed using SPSS version 25 and interpreted as tables and figures. Results: A total of 1019 medicines were prescribed in 524 prescriptions and 81.6% (n = 832) were actually dispensed. The percentage of antibiotic, injections and medicine prescribed from Essential Drug List was 33.9% (n = 345),3.5% (n = 36) and 92.3% (n = 941) respectively. The most frequently prescribed class of medicine were antibiotics 33.9% (n = 345). 65.1% (n = 341) were ≥2 medicines and 8.3% (n = 85) had at least one potential DDIs. Among overall DDIs, the monitor closely and serious level was 60% (n = 51) and 11.8% (n = 10) respectively. The average prescription error was 4.3. Prescription errors due to failure to mention diagnosis was 40.6% (n = 213). Conclusion: Based on findings, the prescribing practices had defects to the optimum value recommended by WHO and showed high prescription errors. Antibiotics prescribing was the major problem in practice. Remarkable DDIs were observed in prescribed medicines. Therefore, designing and implementing policy to improve medicine use practice is highly indispensable.

Retrospective review of medicine utilization for noncommunicable diseases in three public sector pharmacies in Jamaica

Objective

The rational use of medicines offers a cost-saving strategy to maximize therapeutic outcomes for developing and developed countries. The aim of this study was to evaluate the rational use of medicines for selected noncommunicable diseases (NCDs) at three pharmacies at public hospitals in Jamaica using the World Health Organization's (WHO's) prescribing indicators.

Methods

In this retrospective cross-sectional study, prescriptions for adult outpatients containing at least one medicine for cardiovascular disease, diabetes, cancer, chronic obstructive pulmonary disease or asthma that were filled between January and July 2019 were reviewed using WHO's prescribing indicators for the rational use of medicines. Data were analyzed and expressed as descriptive and inferential statistics. For all analyses conducted, significance was determined at P < 0.05.

Results

A total of 1 500 prescriptions covering 5 979 medicines were reviewed; prescriptions were mostly written for female patients aged 42-60 years. Polypharmacy was observed in 35.6% (534) of prescriptions, and there was an average of 4 medicines per prescription, with a maximum of 17. Most of the prescriptions at each site were filled, with the main reason for not dispensing a medicine being that it was out of stock. Generic prescribing was high for all sites, accounting for more than 95% (5 722) of prescribed medicines. There was full compliance with prescribing according to the WHO Model List of Essential Medicines at two of the sites, but it was just off the target at Site 1, by 1.4%.

Conclusions

The WHO guidelines for the rational use of medicines were followed with respect to the proportion of medicines prescribed from the WHO Model List and the proportion of antibiotics prescribed. The number of medicines per prescription and the proportion of medicines prescribed by generic name did not meet the WHO criteria. However, prescribing was aligned with treatment guidelines for the selected NCDs.

Assessment of frequency and types of drug interactions in intensive care units: a cross-sectional study

Background

Drug interactions can cause adverse reactions, from treatment inefficiency to serious treatment complications in the patient. Due to the complexity of drug therapy and the simultaneous use of several drugs and different drug groups, patients hospitalized in intensive care units are exposed to more drug interactions. Therefore, this study was conducted to investigate the frequency of drug interactions in patients hospitalized in the ICU.

Methods

In this cross-sectional study, the files of 300 patients hospitalized in the ICU were examined. Drug interactions were determined using Lexicomp software and the book drug iteration facts. Data analysis was done using SPSS 21 software.

Findings

The findings showed that there were a total of 1121 cases of interference. Two hundred thirty-one (77%) patients had moderate interference, 94 (31.3%) patients had mild interference, and 67 patients (22.3%) had severe interference. One hundred eight patients had B-type interference, 223 C-type interference, 116 D-type interference, and 6 X-type interference, so most of the interactions are C-type interference. One hundred eighty-six patients had pharmacokinetic interference and 201 patients had pharmacodynamics interference. The highest interaction was between two drugs, heparin and aspirin with 58 cases.

Conclusion

This study highlights the alarming frequency and types of drug interactions observed in ICU. The high prevalence of drug interactions emphasizes the need for improved medication management and vigilance in these critical care settings. Polypharmacy and certain drug combinations were identified as major contributing factors to the occurrence of drug interactions, which calls for regular medication reviews and cautious prescribing practices.

Prescribing Pattern and Associated Factors in Community Pharmacies: A Cross-Sectional Study Using AWaRe Classification and WHO Antibiotic Prescribing Indicators in Dire Dawa, Ethiopia

BACKGROUND

Antimicrobials are drugs that are more likely to trigger the development of resistance naturally. Thus, they need to be prescribed, dispensed, and administered with greater caution. To underline the significance of their proper usage, antibiotics are divided as AWaRe: Access, Watch, and Reserve. Timely evidence on medicine use, prescribing patterns, and the factors affecting prescribing of antibiotic and their use percentage from AWaRe classification would help decision-makers to draft guidelines that can enable more rational use of medicines.

METHODS

Prospective and cross-sectional study was conducted among seven community pharmacies in Dire Dawa to assess current prescribing practices related World Health Organization (WHO) indicators and AWaRe classification including antibiotic use and associated factors. Using stratified random sampling techniques, 1200 encounters were reviewed between 1 October and 31 October 2022, and SPSS version 27 was used for the analysis.

RESULTS

The average of medications per prescription was 1.96. Antibiotics were included in 47.8% of encounters, while 43.1% were prescribed from the Watch groups. In 13.5% of the encounters, injections were administered. In multivariate models, patient age, gender, and the number of medications prescribed were significantly associated to prescription of antibiotics. Antibiotics were about 2.5 times more likely to be prescribed to patients under the age of 18 years than to subjects 65 years and older [adjusted odds ratio (AOR): 2.51, 95% confidence interval (CI): 1.88-5.42; P < 0.001]. Men were also more likely than women to receive an antibiotic prescription (AOR: 1.74, 95% CI: 1.18-2.33; P = 0.011). Subjects who received more than two drugs were 2.96 times more likely to receive an antibiotic drug (AOR: 2.96, 95% CI: 1.77-6.55; P < 0.003). The probability of prescribing antibiotics was increased by 2.57 for every one-unit increase in the number of medications [crude odds ratio (OR): 2.57; 95% CI: 2.16-3.47; P < 0.002].

CONCLUSION

According to the present study, the amount of prescriptions with antibiotics at community pharmacies is much higher than the WHO standard (20-26.2%). The antibiotics prescribed from Access group were 55.3%, which is slightly lower than WHO recommended level (60%). The prescribing of antibiotics was significantly correlated to the patient's age, gender, and number of medications.

Understanding conflicts of interest in rational drug prescription in a developing country: A stakeholder analysis, healthcare guidelines and ethical public health issues

Background

Rational drug prescription (RDP) is one of the main components of the healthcare systems. Irrational prescribing can bring about numerous negative consequences for the patients and governmental agencies. This study aims to analyze the involvement of stakeholders in rational drug prescribing, their position (opponent or proponent), and the rationale behind it.

Methods

This was a qualitative study conducted in 2019. Semi-structured face-to-face interviews were conducted with 40 stakeholders. Purposive and snowball sampling techniques with maximum heterogeneity were adopted to select the interviewees. Data was analyzed by MAXQDA software using thematic approach.

Results

Iranian Food and Drug Administration employs the highest authority on the rational prescribing policy. Although the Ministry of Health and Medical Education, the Social Security Organization as one of the main health insurance organizations, pharmaceutical companies, and the Medical Council of the Islamic Republic of Iran, are among agencies that have great authority to improve rational prescribing, they fail to act professionally as they have conflicting interests. Remarkably, the Iran Food and Drug Administration, insurance organizations, family physicians, and patients, highly support the rational prescribing policy while the pharmaceutical companies display the least support for it.

Conclusions

To make the prescription and using drugs more rational, policy makers should focus on different sources of conflicts of interest that different actors have. They should devise legal, behavior and financial policies accordingly to lessen or at least neutralize these conflicting interests, otherwise achieving RDP would be impossible in short and long terms.

Economic impact of clinical pharmacist interventions in a general tertiary hospital in Qatar

BACKGROUND

With an increasingly strained health system budgets, healthcare services need to continually demonstrate evidence of economic benefits. This study sought to evaluate the economic impact of interventions initiated by clinical pharmacists in an adult general tertiary hospital.

METHODS

A retrospective review of clinical pharmacist interventions was carried out throughout follow-up durations in March 2018, July/August 2018, and January 2019 in Hamad General Hospital (HGH) at Hamad Medical Corporation (HMC) in Qatar. The study included clinical pharmacy interventions data of patients admitted to the internal medicine, critical care, and emergency wards. Included interventions were documented by clinical pharmacists or clinical pharmacy specialists, and approved by physicians. Interventions by non-clinical pharmacists or with missing data were excluded. Adopting the perspective of HMC, we calculated the total economic benefit, which is the sum of the cost savings and the cost avoidance associated with the interventions. Cost savings was defined as the reduced cost of therapy associated with therapy changes minus the cost of intervention and cost avoidance was the cost avoided by eliminating the occurrence of adverse drug events (ADEs). Sensitivity analyses were performed to assess the robustness of results against uncertainties.

RESULTS

A total of 852 interventions, based on 340 patients, were included. The analysis projected an annual total benefit of QAR 2,267,036 (USD 621,106) based on a negative cost-savings of QAR-175,139 (USD-47,983) and a positive cost avoidance of QAR741,898 (USD203,260) over the 3-month follow-up period. The uncertainty analysis demonstrated the robustness of outcomes, including a 100% probability of positive economic benefit.

CONCLUSIONS

The clinical pharmacist intervention was associated with an increased cost of resource use, which was overtaken by the cost avoidance generated. The pharmacy intervention, therefore, is an overall economically beneficial practice in HGH, reducing ADEs with considerable consequential positive economic savings.

Antibiotic utilization pattern in treatment of acute diarrheal diseases: the case of Hiwot Fana Specialized University Hospital, Harar, Ethiopia

BACKGROUND

The vast majority of acute diarrheal diseases are self-limiting and do not require treatment on a regular basis. Empirical antibiotics should only be used to treat dysenteric and invasive bacterial diarrhea. Antibiotic misuse in the treatment of acute diarrhea is widespread in clinical practice worldwide. Hence, the purpose of this study was to examine the pattern of antibiotic use for the acute diarrheal diseases at Hiwot Fana Specialized University Hospital, Harar, Ethiopia.

METHODS

A retrospective, institution-based cross-sectional study was conducted to investigate the antibiotic utilization pattern for the treatment of acute diarrheal diseases from September 1 to September 30, 2022. Data were obtained retrospectively from patient cards treated for diarrheal disorders from August 1, 2021 to August 31, 2022, using standardized questionnaires, and the analysis was performed using IBM SPSS Statistics version 27.

RESULTS

Among 332 patients in present study, 271 (81.63%) of them received nine different types of antibiotics, with the most commonly prescribed drugs were Cotrimoxazole (30.26%), Ciprofloxacin (19.19%), and Azithromycin (17.71%). Based on the presence of blood in the stools, 14.76% of the cases were invasive bacterial in nature. Antibiotics were prescribed about 2.55 times more frequently to patients under the age of 12 than to subjects 65 and older (AOR 2.55, 95% CI 1.45-3.87). Patients who received three or more medications were 2.77 times more likely to be prescribed antibiotics (AOR 2.77, 95% CI 1.84-7.56). For every unit increase in the number of drugs prescribed, the odds of prescribing antibiotics increased by 2.44 units (COR 2.44; 95% CI 2.06-4.32).

CONCLUSIONS

The current study found that antibiotics were overused in both adults and children with acute diarrheal diseases at Hiwot Fana Specialized University Hospital. The number of antibiotics prescribed was significantly associated with the patient's age and the number of medications prescribed. To reduce antibiotic overuse, health professionals have to follow the national standard treatment guidelines.

Assessment of rational use of medicines for chronic non-communicable diseases: A cross-sectional design in a public access clinic in Jamaica

Background:

Rational use of medicines (RUM) offers a cost-saving strategy to maximize therapeutic outcomes. The aims of this study were to assess RUM for chronic non-communicable diseases (NCDs) using the World Health Organization’s (WHO) prescribing indicators in a public access facility and to evaluate the alignment of the use of drugs with therapeutic recommendations/guidelines.

Design and methods:

In this retrospective cross-sectional study, prescriptions of adult patients containing at least one drug for chronic NCDs, filled between January and July 2019 were reviewed using the WHO prescribing indicators for RUM. Data were analyzed and expressed as descriptive statistics. Associations were determined using chi-square tests, correlations using Pearson’s correlation and medians compared using Mann-Whitney U test. For all analyses, significance was determined at p < 0.05.

Results:

Of the 571 prescriptions reviewed, most were for female, elderly patients with mean age of 69 years, predominantly with hypertension and/or diabetes. Polypharmacy was noted for 53.6% of prescriptions, primarily in elderly patients (p < 0.001), with the median number of five drugs prescribed and three dispensed. Of the drugs prescribed, 76.6% used generic prescribing, 63.3% were dispensed as written and 3.9% were antibiotics prescribed mainly for asthmatic patients (χ² = 74.9, p < 0.001). Drugs prescribed for NCDs were aligned to therapeutic guidelines, but a significantly higher proportion of diabetes medications, (metformin and gliclazide), and cardiovascular medications (enalapril and losartan), were not dispensed as written (χ² = 40.0, p = 0.007).

Conclusion:

This research indicates that there is positive alignment with recommended therapeutic guidelines, however, based on WHO prescribing factors, strategies to improve RUM in this setting are highly recommended.

Systematic review and meta-analysis of medicine use studies in Ethiopia using the WHO patient care indicators with an emphasis on the availability of prescribed medicines

OBJECTIVE

To collate the findings of studies on patient care indicators in Ethiopia using the WHO/International Network for Rational Use of Drugs indicators with a focus on the availability of medicines to patients.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Embase, Global Index Medicus, Google Scholar, Medline (via PubMed) and Web of Science.

ELIGIBILITY CRITERIA

Medicine use studies employing the WHO patient care indicators across health facilities in Ethiopia.

DATA EXTRACTION AND SYNTHESIS

Descriptive summary of the indicators and a random-effects meta-analysis were performed for quantitative synthesis of findings on the percentage of medicines actually dispensed. Meta-regression was performed to assess the moderator effects of different attributes of the studies.

RESULTS

A total of 25 studies conducted in 155 health facilities with 11 703 patient exit interviews were included. The median value of average consultation time was 5.1 min (25th-75th: 4.2-6.6) and that of average dispensing time was 78 s (25th-75th: 54.9-120.0). The median percentage of medicines with adequate labelling was 22.4% (25th-75th: 5.6%-50.0%). A concerning trend of decreasing dispensing times and adequacy of labelling were observed in more recent studies. The median percentage of patients with adequate knowledge of dosage schedules of medicines was 70.0% (25th-75th: 52.5%-81.0%). In the meta-analysis, the pooled estimate of medicine availability was 85.9% (95% CI: 82.1% to 89.0%). The multivariable meta-regression showed that geographical area and quality of study were statistically significant predictors of medicine availability.

CONCLUSION

Short consultation and dispensing times, inadequate labelling, inadequate knowledge of patients on medicines and suboptimal availability of medicines were identified in health facilities of Ethiopia. Studies aimed at further exploration of the individual indicators like problems of inadequate labelling and patients' knowledge of dispensed medicines are crucial to determine the specific reasons and improve medicine use.

The Pattern of Medicine Use in Ethiopia Using the WHO Core Drug Use Indicators

Introduction

Rational medicine use is an appropriate prescribing, dispensing, and patient use of medicines for the diagnosis, prevention, and treatment of diseases. It is affected by several factors. Irrational use of medicine is a widespread problem at all levels of care. This review is aimed at assessing the medicine use pattern in health facilities of Ethiopia using the medicine use pattern developed by WHO/INRUD.

Methods

Relevant literature was searched from Google Scholar, PubMed, Hinari, Web of Science, and Scopus using inclusion and exclusion criteria. A systematic review was used to summarize the medicine use pattern in health facilities of Ethiopia, and that WHO core drug use indicators were employed.

Result

From 188 searched studies, 30 literatures were reviewed. The average number of drugs per encounter was 2.11. The percentage of encounters with antibiotics and injection was 57.16% and 22.39%, respectively. The percentage of drugs prescribed by generic name and from an essential drug list was 91.56% and 90.19%, respectively. On average, patients spent 5.14 minutes for consultation and 106.52 seconds for dispensing. From prescribed drugs, 67.79% were dispensed, while only 32.25% were labeled adequately. The availability of key essential medicines was 64.87%. The index of rational drug use value was 7.26. Moreover, the index of rational drug prescribing, index of rational patient-care drug use, and index of rational facility-specific drug use were 3.74, 2.51, and 1.01, respectively.

Conclusion

Ethiopian health facilities were faced with antibiotic overprescribing, short consultation, and dispensing times, poor labeling of medicines, poor availability of key drugs, and nonadherence to the essential drug list. Routine, multidisciplinary awareness creation, and regulation should be implemented to promote rational medicine use at a national level.

Antibiotic-prescribing pattern in the outpatient departments using the WHO prescribing indicators and AWaRe assessment tool in a tertiary-care hospital in South India

Context:

Rational drug use has a great role of influence in health care. The fact sheet given by the World Health Organization (WHO) shows that around 50% of the drugs are prescribed, dispensed, and sold inappropriately. One of the major consequences of irrational drug use in infections is antibiotic resistance.

Aim:

The present study aims to assess the antibiotic-prescribing pattern by auditing the prescriptions in a teaching hospital.

Settings and Design:

A prospective cross-sectional study was conducted in the pharmacy of a teaching hospital to evaluate the prescriptions of the outpatient department.

Materials and Methods:

The prescriptions used to treat symptoms suggestive of infections were taken into consideration. A total of 1,000 prescriptions were analyzed.

Data Analysis:

The data was analysed using Microsoft Excel.

Results:

A total of 2,536 drugs were prescribed. The average number of drugs per prescription was 2.5. The percentage of encounters with antibiotics prescribed was 17.5%. The percentage of encounters prescribed with a generic name and with drugs from the essential drug list was 87.5% and 65%, respectively. There were no injections prescribed. Amoxicillin and ciprofloxacin were the most common antibiotics prescribed. The duration of the treatment was mentioned in all the prescriptions.

Conclusions:

Our study shows that the percentage of antibiotic usage is within the WHO standard value. The average number of drugs per prescription was slightly higher than the WHO value. Steps should be taken to improve the generic prescribing by the physicians.

Drug utilization pattern and rational drug use at orthopedics and traumatology outpatient clinics: A cross-sectional study

Objectives

The aim of the present study was to assess the prescriptions of patients who were admitted to the orthopedics and traumatology outpatient clinic of a tertiary care hospital according to the WHO prescribing indicators.

Patients and methods

Between January 2020 and March 2020, a total of 1,024 patients (273 males, 751 females; mean age: 51.9±13.9 years; range, 19 to 103 years) were included in the study. Only patients who were prescribed drugs and 18 years of age or older were included in the study. The WHO core prescribing indicators were utilized for the assessment of rational drug use. The WHO prescribing indicators percentages between the age categories were analyzed. The average number of drugs between the age categories was also examined.

Results

The average number of drugs per encounter was 2.9. The percentage of encounters with an antibiotic prescribed was 2.6% and with an injection prescribed was 10.7%. The percentage of drugs prescribed from essential drugs list was 33.8%. There were no prescriptions consisting generic name of drugs (0%). Polypharmacy was significantly higher in the ≥65 age group compared to the 18-44 age group (p=0.001).

Conclusion

The percentage of encounters with an antibiotic and injection prescribed were optimal according to WHO standards, while the average number of drugs per encounter was higher than the WHO ideal ranges. Unfortunately, the parameters such as the percentage of prescribing with generic name and from essential drug list was far more behind the optimal range.

WHO/INRUD Core drug use indicators and commonly prescribed medicines: a National Survey from Sri Lanka

Background

Identification of internationally comparable indicators of medicines use are important for a country to implement strategies and regulations to improve usage of medicines. Sri Lanka established a new National Medicines Regulatory Authority in 2015 and this survey evaluated the medication use indicators in Sri Lanka, according to the International Network on Rational Use of Drugs (INRUD), prior to its implementation.

Methods

This descriptive-cross-sectional study was conducted in 80 pharmacies, representing all 25 districts of the country. Three pharmacy categories were included; privately owned pharmacies, ‘Rajya Osusala’ pharmacies operated by the State Pharmaceuticals Corporation (SPC) of Sri Lanka and SPC Franchisee pharmacy outlets. Selection of pharmacies from respective districts were done proportionate to estimated population. Data were collected to identify WHO/INRUD core drug use indicators and the commonly prescribed medicines.

Results

Total of 2328 prescriptions were included (‘Rajya Osusala 559; SPC Franchise 711; private pharmacies 1058). Altogether 7,255 medicines were prescribed, and the 3 most commonly prescribed medicines were atorvastatin, losartan and metformin. Average number of medicines per encounter was 3.1±1.9 (Median: 3; range 1-12) Highest average number of medicines per encounter was reported in prescriptions received at ‘Rajya Osusala’ pharmacies (3.6±2.2), significantly higher than in other categories of pharmacies (p<0.001). Percentage of medicines prescribed by generic name was only 35.5%, highest at the ‘Rajya Osusala’ pharmacies (40.6%), significantly higher than other categories of pharmacies. The overall percentage of medicines prescribed from essential medicine list (EML) was 68.8%, without any significant variation between different categories of pharmacies. The percentage of medicines actually dispensed and accurately labelled were 92.4 and 98.5% respectively.

Conclusions

The average number of medicines per encounter was higher than the WHO recommended value but the usage of antibiotic and injectable drugs were within recommended standards. Generic prescribing, was very much lower. The EML prescribing, labelling and percentage dispensed medicines fared much better although lower than the WHO recommended 100% compliance. This island wide study has provided national wide data before the implementation of key changes in regulation of medicines in Sri Lanka and a repeat survey will be useful to identify impact of the new legislations.

Rational Drug Use Evaluation Based on World Health Organization Core Drug Use Indicators in Ethiopia: A Systematic Review

Background

Rational use of medicines plays a vital role in avoiding preventable adverse drug effects, maximizing therapeutic outcomes with promoting patient adherence, and minimizing the cost of drug therapy. Irrational use of drugs is often observed in countries with weak health care systems. No review has been done that systematically expresses rational drug use practice based on the three WHO core drug use indicators in Ethiopia. Thus, this study was aimed to review systematically the prescribing, health-facility, and patient-care indicators based on WHO core drug use indicators in Ethiopia.

Methods

A systematic article search was conducted in different electronic databases including PubMed/ MEDLINE, the Cochrane Library, EMBASE, Web of Science, POPLINE, the Global Health, and Google scholar. Quality assessment was conducted using Newcastle-Ottawa quality assessment scale. Studies were synthesized and grouped in to prescribing, patient care and health facility indicators.

Results

From a total of 6239 articles, 21 studies were found suitable for the review. The highest average number of drugs per encounter was 2.5 while the lowest was 0.98. The percentage of generic drug use was ranged from 70.5% to 100%. The highest percentage of encounters with an antibiotic was 85%. The lowest percentage of drugs prescribed from essential drugs list was 81.4%. The highest percentage of drugs actually dispensed and adequately labeled was 96.16% and 96.25%, respectively.

Conclusion

This study showed that the practice of rational drug use varied across region of the country. The average number of drugs per prescription, percentage of drugs encounter with antibiotics, drugs prescribed by their generic name, average consultation time, average dispensing time, percentage of drugs adequately labeled, and availability of essential drugs showed deviation from the standard recommended by WHO. Thus, provision of regular training for prescribers and pharmacists, and ensuring the availability of essential drugs should be encouraged.

Drug use pattern using WHO core drug use indicators in public health centers of Dessie, North-East Ethiopia

Background

Rational drug use requires that patients receive and take medication appropriately. Though the process of diagnosis and pharmaceutical care is complex, World Health Organization (WHO)/international network for rational use of drugs (INRUD) core drug use indicators investigate drug use to minimize the hazardous effect of the drug and enhance the wise use of scares resources. This study assessed drug use patterns in health centers of Dessie town using WHO/INRUD indicators.

Methods

A cross-sectional study was conducted in public health centers of Dessie town. Data were retrospectively collected from 1500 prescriptions dispensed from January 1, 2018, to December 31, 2018 using WHO data collection tool to assess prescribing indicators. For patient care and health facility indicators, 600 patients and 3 health centers were prospectively reviewed. Systematic random sampling was used to select samples. Data were analyzed using the Statistical Package for the Social Sciences version 20.

Results

The average number of drugs per encounter was 2.1. The percentage of encounters with antibiotics and injection was 44% and 13.9%, respectively. The percentage of drugs prescribed by generic name and from an essential drug list was 98% and 100%, respectively. On average, patients spent 4.7 min for consultation and 105 s for dispensing. From 1305 prescribed drugs, 92% were dispensed, while only 4% were labeled adequately. More than half (54.8%) of patients had adequate knowledge of their medication. None of the health centers had an essential drug list. The availability of key essential medicines was 64.10%.

Conclusion

This study demonstrated irrational drug use practices in all healthcare facilities. Polypharmacy, antibiotics over-prescribing, short consultation and dispensing times, inadequate labeling of medicines, inadequate level of patients' knowledge about prescribed medicines, and unavailability of key drugs in stock were found to be the major problems. Continuous refreshment trainings on rational use of drugs and WHO recommendations should be given for prescribers and pharmacists. Further, we recommend studies involving large number of facilities to estimate overall prescribing practices.

Evaluation of Rational Use of Medicine Using WHO/INRUD Core Drug Use Indicators at Teda and Azezo Health Centers, Gondar Town, Northwest Ethiopia

Background

Despite medicines are a major contributor to the health and well-being of the community, irrational use of medicines is being a serious public health crisis with significant harmful implications for patients, healthcare systems, and communities as a whole.

Objective

This study was aimed at evaluating the rational use of medicine using the World Health Organization/Network of Rational Use of Drugs (WHO/INRUD) core drug use indicators at Teda and Azezo health centers of Gondar town, northwest Ethiopia.

Methods

A cross-sectional study was conducted among 1200 prescription papers retrospectively, and 60 patients prospectively at two health centers of Gondar town, northwest Ethiopia from May 01/2019 to April 30/2020. The data were collected using a standard data collection checklist. Data were analyzed using SPSS^® version 24. The data were analyzed descriptively by using mean, frequency, and proportion.

Results

Prescribing indicators: From a total of 2595 prescribed medicines, 94% of them were prescribed by generic name; percent encounters with injection was 9.5±0.28%, percent encounters with antibiotics was 73.85±0.35%, and 100% of medicines were prescribed from the essential medicine list of Ethiopia. Patient care indicators: Only 16.7% of the patients knew the correct dosage of their medications, and 17.5% of dispensed medicines were adequately labeled. From the prescribed medications, only 77.17% were actually dispensed. Average consultation and dispensing time were 5.35 minutes and 40.24 seconds, respectively. Facility-specific indicators: Only 83.5% of key medicines were available in the health centers.

Conclusion

According to the WHO/INRUD core drug use indicators, rational medicine use is not achieved in terms of most components of the prescribing, patient care, and facility-specific indicators. Therefore, both health centers should work towards promoting the rational use of medicines.

Evaluation of drug prescription pattern using World Health Organization prescribing indicators in public health facilities found in Ethiopia: systematic reviews and meta-analysis

BACKGROUND

Drug use evaluation is a structured, methodological, and criteria-based drug assessment system that helps to evaluate the actual trend of drug use in a particular setting. If drug prescription practices are inappropriate, need to examine the patterns of drug use is necessary to change prescribing patterns accordingly. Therefore, this review aimed to determine the drug prescription pattern in public health facilities found in Ethiopia using prescribing indicators developed by the World Health Organization.

METHODS

This review was conducted as per the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline. Extensive searching to identify articles was conducted in PubMed, Medline, Web of Science, Research Gate, Africa Journal of Online, and Google scholar. Finally, 10 eligible articles were selected for analysis based on inclusion and exclusion criteria. The median value, as well as the 25th and 75th percentiles for each WHO prescribing indicator, were computed.

RESULT

The pooled median value of WHO prescribing indicators was reported as follows: the average number of drugs prescribed per encounter = 2.14 (IQR 1.79-2.52), the percentage of encounters with antibiotics prescribed = 43.46% (IQR 30.01-58.67), the percentage of encounters with an injection prescribed = 13.20% (6.47-40.7), percentage of drugs prescribed by generic name = 93.49% (89.13-97.96), and the percentage of medicines prescribed from essential medicines list = 92.54% (85.10-97.7). The forest plots determined for each prescribing indicator indicated that there is a high degree of heterogeneity across articles.

CONCLUSION

All of the prescribing indicators were not consistent with the standard values recommended by the World Health Organization. Therefore, public health facilities should take appropriate measures for improving the prescription patterns as per the recommendation set by the World Health Organization.

Evaluation of Medicine-Use Pattern Using World Health Organization's Core Drug-Use Indicators and Completeness of Prescription at University of Gondar Comprehensive Specialized Hospital, Gondar, Ethiopia: Cross-Sectional Study

Background

Rational use of medicines is patients receiving medicines appropriate to their diagnosis in doses that meet their requirements for an adequate period of time at an affordable price. Irrational prescribing practices result in ineffective, unsafe treatment, prolong prognosis, and increase health-care costs, and this is a common phenomenon in Ethiopia. The aim of this study was to evaluate medicine-use pattern using World Health Organization core drug-use indicators and completeness of prescription at the University of Gondar Comprehensive Specialized Hospital.

Methods

A retrospective and prospective cross-sectional descriptive study was conducted at the dispensing pharmacy units of the health facility from March 2019 to May 2019 using a systematic random sampling technique. Data were analyzed using SPSS version 24.0, and results are presented using tables.

Results

A total of 1,128 medicines were covered in the analyzed sample. The response rate, using standard prescription paper was found to be 100%. Mean number of medicines per prescription was 1.88. The proportion of medicines actually dispensed was 74.56%, and 91.4% medicines were prescribed by their generic names. Among prescribed medicines, antibiotics accounted for 37.5%, and 20% of the prescribed medicines were injectable. Prescriptions containing patient name, identification number, age, and sex comprised 99.8%, 99.5%, 91.8%, and 94.5%, respectively of the total. Prescriptions signed by prescribers accounted for 96.2%, however, only 75.8% of prescribers wrote their name. Moreover, only 4.8% of dispensers printed their name, and 32.7% of prescriptions were signed by pharmacists. Patient-care indicators were found to be below standard.

Conclusion

Most prescriptions were incomplete, and prescribers by far completed their role than dispensers. The health facility has standard prescription paper and updated pharmaceuticals list. Percentages for encounters with antibiotics, prescribing by generic name, and patient-care indicators deviated from the standard. The dispensing and counseling time also far from the standard, and most medicines were not labeled.

Drug Use Evaluation of Beta-Blockers in Medical Wards of Nedjo General Hospital, Western Ethiopia

Introduction

Beta-blocker use evaluation is a performance method that focuses on the evaluation of beta-blocker use processes to achieve optimal patient outcomes. Several studies conducted in different hospitals revealed a high incidence of inappropriate prescription of beta-blockers among hospitalized patients. Therefore, it is important to identify inappropriate beta-blocker prescribing since they may increase the risk of hospitalizations. Despite this, there was no study conducted related to drug use evaluation of beta-blockers in Nedjo general hospital (NGH). Thus, this study was aimed at assessing the use evaluation of beta-blockers in medical wards of NGH.

Methods

A retrospective cross-sectional study was conducted at medical wards of NGH from January 1, 2016, to December 31, 2017.

Results

Out of the total of 149 medical record of patients that contains beta-blockers, 84 (56.37%) were males and about one-third (31.54%) of the patients ages were between 41 and 50 years. Propranolol was the most commonly prescribed beta-blocker (62.76%), and 94.56% of beta-blockers were prescribed with correct indication. There were about 51%, 46.31%, 64.43%, and 46.98% of beta-blockers prescribed with the correct dose, duration, frequency, and route of administration, respectively. Regarding the routes of administration, 70 (46.98%) of them were prescribed with the correct route. Most drugs interacting were propranolol with cimetidine 26 (68.42%), and the most frequent condition for which beta-blockers were prescribed was hypertension (32.89%).

Conclusion

Overall, there was an inappropriate use of beta-blockers in terms of dosage and durations. So, prescribers of NGH should strictly adhere to the national treatment guideline when prescribing medications. Additionally, drug information centers have proved useful and effective in promoting rational drug use. Hence, it should be recommended for general use.

Drug prescribing patterns in pediatric urinary tract infections: A retrospective drug utilization analysis in an urban tertiary care hospital

Introduction:

A constant update of antibiotic sensitivity of pathogens of the area, country, or institution helps in interventions that would improve the prescribing pattern and rational use of drugs in children. This study aimed to assess prescribing trends for urinary tract infection (UTI), a common distressful pediatric infection in a tertiary care teaching hospital.

Materials and Methods:

This study was a descriptive, retrospective, cross-sectional, and record-based analysis including pediatric patients aged <18 years of either gender diagnosed with UTI. The case record files retrieved from medical records department based on the International Classification of Diseases, 10th Revision (ICD-10) disease coding were analyzed for demographics, and details of drugs including dose and route of administration, frequency, and duration of treatment with antimicrobial used and other concurrent drugs were recorded.

Results:

Of 42 patients included in the study, 14 (33.3%) were males and 28 (66.67%) were females. Third-generation cephalosporins were the most commonly used antibiotics (71.4%) followed by aminoglycosides (35.7%), amoxicillin clavulanate (11.9%), fluoroquinolones (7.1%), and miscellaneous (doxycycline, metronidazole, and nitrofurantoin) (9.5%). Ceftriaxone among the cephalosporins and amikacin among the aminoglycosides were the most commonly used drugs. Intravenous route was the most commonly used route of administration followed by patients who received by both intravenous and oral routes. The average duration of therapy was 4.43 ± 1.9 days.

Conclusion:

This study concludes that third-generation cephalosporin is used as first-line drugs irrespective of the causative agent for UTI which should ideally be reserved for complicated UTIs. Moreover, existing guidelines also indicate that the duration of antimicrobial therapy should be seven to 14 days. These results highlight the necessity for a remedial education program within the health care system designed to improve pharmacotherapy of UTI.
